... If 72.0 grams of H2O are formed from the reaction, how much heat was released? = 73.9 kJ 3. Hess' Law: The value of H for a reaction is the same whether it occurs directly or in a series of steps (state function). Htotal = H1 + H2 often used to calculate H for one step, knowing H for all steps and ...

... established even when there is disorder (entropy). Spontaneous change is a change that will, once begun, continue on its own under a given set of conditions and it will not require a continuous supply of energy. So a non spontaneous reaction is one that needs continual energy input to continue. ...

... At what energy level should you put the activated complex, the top of the peak? Since E a forward = +40 kJ, you know that from the initial reactants (A + B) you need to go up 40 energy units. Pick any value for a starting energy level (let's use a starting point of 10 here), then add 40 to find the ...

This is because each ion absorbs light of certain wavelengths only in the visible past of the spectrum, thus changing incident white light into light whose hue () is composed of the colours complementary those which have absorbed. The d-level is split into two when a complex ion is formed and diffe ...
